OK, DIY Warriors ... Here is the outcome ...
1. Checking with multimeter across the input side resulted in no voltage. However, using a tickler gave a reading of AC current present. HUH? Yes, the old induced voltage false reading!
2. Checking with a clamp meter indicated no voltage inside the WH, at the input side ... HUH?
3. Shut down the building to avoid working on a hot panel.
4. Changed out the breaker, which had been invented by Edison it was so old. Upgraded to 30A from 20A ... yes, the #10 wires would support it.
5. Powered up the building and TAH DAH! Measured 220 across the input side of the manual cut off. Engaged the entire circuit and TAH DAH! Got 220 inside the WH.
Lessons learned: (1) the AC tickler is a good tool but induced voltage can trick you. (2) believe your better diagnostic tools (multimeter and clamp meter).
Thanks for everybody kicking in on ideas ... Great team here!
